INCUBATOR.

Application filed August 24, 1923. Serial No. 659,218

To all whom it may concern:

Be it known that I, Mosns E. Lewis, a citizen of the United States,residing at Tolar, in the county of Hood and State'of Texas, haveinvented new and useful Improvements in Incubators, of which thefollowing is aspecification.

This invention relates to incubators and contemplates a strong andsimple construction, with a novel construction of means for regulatingthe temperature of the incubator.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numeralsofreference indiparts in the several views, and wherein:

Figure 1 is a front elevation of the incubator.

Figure 2 is a view taken at a right angle to Figure 1 with the door openshowing the tray partly removed.

Figure 3 is a top plan View.

Figure 4 is a sectional View taken on the line 4-4 of Figure 2, showingthe normal position of the heat regulator.

Figure 5 is a similar view showing the active position thereof.

Figure 6 is a detail view of the radiator.

Referring to the drawings in detail, 10 indicates the body of theincubator which of course can be constructed from any suitable material,and vary in size and configuration without departing from the spirit ofthe invention. The body is preferably of rectangular formation in plan,and the bottom is provided with a plurality of air inlet openings 11.One side of the body is provided with a door opening, normally closed bya hinged door 12, and this of course permits access to be had to theincubator, and also allows the tray 13 to be conveniently inserted andremoved from the body portion when desired. The door of course is heldclosed by any suitable means and is further provided with a sightopening 14, although all the walls may be provided with such openings ifdesired which openings are covered by suitable transparent material.The'tray slides upon and is supported by cleats which are secured to theopposite walls of the body 10 thereby spaclng the tray a slightdistancefrom the bottom of the incubator.

The incubator is heated by a heater 18 which may be of any suitableconstruction, the heater being preferably in the form of a lamp as shownwhich is supported upon a platform or base 19 secured to one end of abracket 20 which in turn is suspended from one side wall of theincubator. Arranged immediately above this heater and supported by theadjacent side wall of the incubator is a casing 21 having an opening inthe bottom thereof, indicated at 22 to receive the heat from the heateras is obvious. This casing 21 is slotted as at 23 and this slotcoincides with a slot 24 formed in the adjacent side wall oftheincubator to receive the neck portion 25 0f a radiator 26. This radiatoris of a size and shape to snugly accommodate itself within the body ofthe incubator and is supported immediately above the trayabovementioned. The neck portion 25 communicates with a water container27 which container surrounds a chirn- I ney 28 through which theproducts of combustion pass as they enter the opening 22 in the bottomof the container 21. Of course the water container 27 is connected withthe chimney 28, so that the chimney and radiator may be removed as aunit from the incubator at any time desired, and for any purposewhatsoever. The top of this water container 27 is provided with a waterinlet 29, so that the container and radiator can be supplied with thenecessary amount of water, which of course radiates heat and maintainsthe incubator at a proper temperature.

For the purpose of regulating the temperopening being normally closed bya damper.

34 which reposes upon the top of the incubator but carried by one end ofa lever 32 pivoted at a point between its ends on a suit able bracket33, which in turn is attached to the top of the incubator. The other endof this lever 32 is bifurcated as at 35 to receive a rod 36 which passesupwardly through an opening in the top of the incubator for a purpose tobe hereinafter described. Arranged in end to end relation with the lever32 is another longer lever 37, the latterbeing pivoted as at 38 on asuit ablebracket 39 also secured to the top of the incubator, Iheadjacent ends of these levers 3.2 and 37 respeaively overlap, so thatthe former is actuated by the latter when, it

is tilted upon its pivot in one direction.

threaded at its upper end to: receive a nae 42 which: ottourse repose'supon the upper surface oi the level: This ro'dv36 depends from the coverintotheihcubator and. isterminally connected with the adjacent. end of aweighted lever 44:," the latter being fulcrumed between its ends a-sat 5upon the bifiircated: extremity of a substantially [L- shaped. bracketarm 46 which: is also. secured to the underside of theoover of theincubator.

Also supported on. the Leshaped bracket arm.

4:6 is a thermostat 47. which is riveted or otherwise secured asindicated at. 48.. The inner: endi'or the nee end of the lever'44 isdisposed directly in the path of: expansion of the: thermostat-so; thatupon overheating;

of the incubator the lever 44' will be rocked: and! through theinstrumentality of the parts- 32 and 37 the 'dam per s 34:: and; 41 willbe elevated as indicated in Figure 5-. This will permit the escape ofheat through the open ing 30 and chimney 28.

WVhile it is believed that from the foregoing 'descrip'tioi'i, thenature and advantages oi? the invention will be readily apparent, Idesire to have it understood that I do not limit myself to what isherein shown and described and that such changes may be resorted to whendesired as fall within the scope of what is claimed,

Having thus described "the invention, I claim:
